Well you get what you paid for. I wish companies here in the states took the time, the money and development to make world class parts that these two companies make. How many companies do you know that do wind tunnel testing on their body parts??? I bet your glad these companies don't make any parts for your car, me on the other hand I wish they made more parts for the H22 and the Accord in general. Not like I need to spend anymore money I'm broke as it is.
If I had an S2k I would drop 5k on a mugen hard top, its PIMP!!
In the end I would probably choose Mugen, but Spoon is a very close second. Unfortunately Spoon doesn't make anything for Accord or the H22, damn B series, K series, and f series get all the Luck
